In this introductory course, the participant will learn how to use Radioss to solve highly non-linear transient problems typical of impact. Users will be able to apply Radioss to evaluate product performance under loading that causes large displacements, large strains, contact and material non-linearity. Key theoretical aspects of an explicit solver are explained along with an emphasis on practical application including best practices. Participants will also learn how to build a valid simulation in Radioss by properly choosing elements and properties, and by defining basic material laws, contact and loading.
